    A new Poisson fitting method accurately analyzes flow cytometry data. This technique, validated with macrophage phagocytosis, offers a reliable approach for analyzing cellular uptake and distribution in biological samples.

    Area of Science:

    • Quantitative Biology
    • Biophysical Chemistry
    • Cell Biology

    Context:

    • Flow cytometry is a powerful technique for analyzing single cells.
    • Quantifying cellular processes like phagocytosis requires robust data analysis methods.
    • Traditional analysis methods may not fully capture the distribution of cellular events.

    Purpose:

    • To introduce a novel Poisson fitting method for analyzing flow cytometry data.
    • To estimate distribution parameters using the steepest descent method.
    • To validate the method using an experimental model of phagocytosis.

    Summary:

    • A Poisson fitting method was developed and applied to flow cytometry data.
    • The steepest descent method was used for parameter estimation.
